INCOME TAXES

The Company uses a full year projected effective tax rate approach to calculate year-to-date taxes. In addition, certain items impacting total income tax expense are recorded in the periods in which they occur. The projected effective tax rate is the ratio of projected “Total income tax expense” divided by projected “Income from operations before income taxes”.

The Company's income tax provision, on a consolidated basis, amounted to an income tax benefit of $2.4 million, or (29.5)% of income from operations before income taxes in the first three months of 2018, compared to a benefit of $18.5 million, or (85.3)% of income from operations before income taxes in the first three months of 2017. The Company’s current effective tax rate differed from the U.S. statutory rate of 21% primarily due to non-taxable investment income and tax credits. The Company's prior effective tax rate differed from the U.S. statutory rate of 35% primarily due to non-taxable investment income, tax credits, and domestic production activities deduction. The Tax Cuts and Jobs Act of 2017 ("Tax Act of 2017") modified the methodology for determining the dividend received deduction and will likely reduce the tax benefit of non-taxable investment income in periods starting after December 31, 2017.
